This week Kiyan and Dylan are visited by some very special people… And they’re late, to boot. It’s very weird, but at least it’s somehow related to The Three Doctors, which featured the return of Patrick Troughton and William Hartnell to the role of the Doctor. The serial was written by Bob Baker and David Martin, and it aired from the 30th of December, 1972 through the 20th of January, 1973 as a 10th anniversary special.
